Analyze why Linux processes need to sleep?

Why does a Linux process need to sleep? Linux is a multitasking operating system that supports multiple processes running at the same time. In Linux, a process has three states: running state, ready state and blocked state. Among them, the blocking state is also called the dormant state, which refers to the state where the process temporarily stops running because it is waiting for an event to occur. In order to efficiently utilize computing resources, Linux processes need to enter a dormant state under some circumstances. Waiting for the I/O operation to complete: When the process needs to perform I/O operations, such as reading files, network communications, etc., the process is

Explore why Linux processes go to sleep

Explore why Linux processes go to sleep

The Linux process entering sleep refers to the process of transitioning the process from running state to sleep state. In Linux systems, there are many reasons why a process goes to sleep, including waiting for certain resources, waiting for I/O operations to complete, waiting for signals, etc. In this article, we will explore some common reasons why Linux processes go to sleep and illustrate them with concrete code examples. A resource waiting process may enter sleep state because it needs certain resources, such as waiting for other processes to release a shared resource. In the following example, we create two sub-

What is Linux Bashrc? Detailed interpretation

What is Linux Bashrc? Detailed interpretation

LinuxBashrc is a configuration file in the Linux system, used to set the user's Bash (BourneAgainShell) environment. The Bashrc file stores information such as environment variables and startup scripts required for user login, and can customize the user's Shell environment. In the Linux system, each user has a corresponding Bashrc file, which is located in a hidden folder in the user's home directory. The main functions of the Bashrc file are as follows: setting up the environment

Why does a Linux process enter sleep state?

Why does a Linux process enter sleep state?

Why does a Linux process enter sleep state? In a Linux system, a process may enter the sleep state because factors such as the operating system's scheduling policy, resource allocation, and competition between processes may cause the process to enter the sleep state. The sleep state means that the process cannot be executed immediately and needs to wait for certain conditions to be met before it can continue to execute. Next, we will discuss in detail why the Linux process enters the sleep state, and will also attach specific code examples. A common situation when waiting for an I/O operation to complete is when a process

The Linux operating system is a widely used open source operating system that uses multitasking to manage processes. Process is one of the most important concepts in the operating system. When a program is running, it will be assigned by the operating system as one or more processes. The Linux process can be divided into three parts: process control block (PCB), kernel stack and user stack. This article will introduce the functions of these three parts in detail and give corresponding code examples to illustrate their practical application. 1.
